Brass fittings deliver reliable, long-lasting connections for plumbing, HVAC, gas, and irrigation projects. Their corrosion resistance, high‑temperature tolerance, and tight sealing performance make them a smart choice for both repairs and new installations. Shop brass pipe fittings in common shapes such as couplings, unions, elbows, tees, crosses, caps, plugs, nipples, reducers, and bushings, along with adapters, barbed hose ends, compression bodies, flare nuts, and push‑to‑connect options to match your pipe or tubing.
Benefit from compatibility with copper tube, aluminum, and PEX (using barb and crimp or clamp rings), and make clean transitions to CPVC or steel via threaded or union adapters. Available thread standards include NPT, BSPP/BSPT, SAE flare, and GHT for garden hoses. Select lead‑free, NSF/ANSI‑certified brass for potable water, or DZR (dezincification‑resistant) brass for aggressive water chemistry. Many brass compression fittings are reusable and allow precise, leak‑free service without soldering.
For best results, size fittings by the correct standard: nominal pipe size for threaded pipe, outside diameter for tubing, and hose ID for barbed ends. Use PTFE tape or approved pipe thread sealant on tapered threads, but avoid sealant on compression and flare seats. Cut tubing square, deburr, align carefully, and tighten to the manufacturer’s torque to prevent leaks or cracked components. Verify pressure and temperature ratings for your medium—water, air, fuel, or gas—and check local code requirements before installation. Periodically inspect connections after thermal cycling and retighten or replace ferrules as needed. With durable construction, easy machinability, and broad availability, brass fittings help you repair, upgrade, and expand plumbing systems quickly and confidently. Browse our selection to buy the right brass fittings, compression fittings, adapters, and valves online, matched by size, thread type, and application.
